Try these steps in order:
- Reset the graphics driver:
- Press Windows + Ctrl + Shift + B.
- A beep or screen flicker indicates it worked.
- Try the security screen:
- Press Ctrl + Alt + Del.
- If that appears, open Task Manager.
- Restart Windows Explorer:
- In Task Manager, find Windows Explorer.
- Right-click it and select Restart.
- If it is not listed, select File > Run new task, type explorer.exe, and press Enter.
- Check display output mode:
- Press Windows + P, then press P again and Enter to cycle display modes.
- This helps if Windows is sending the desktop to the wrong display.
- If the screen stays blank, boot into Safe Mode:
- Hold the power button for 10 seconds to force shutdown.
- Repeat this 2–3 times until Windows enters Recovery Mode.
- Go to Troubleshoot > Advanced Options > Startup Settings > Restart.
- Press F5 for Safe Mode with Networking.
- In Safe Mode, check the graphics driver:
- Open Device Manager.
- Expand Display adapters.
- Right-click the GPU and choose Update driver.
- If the issue started after a driver update, choose Roll back driver instead.
- If the problem started recently, use System Restore:
- From Recovery Mode, go to Troubleshoot > Advanced Options > System Restore.
- Choose a restore point from before the issue started.
- If the issue happens after sign-in and the desktop never loads:
- Press Windows + R, type regedit, and press Enter.
- Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. - Check that the Shell value is set to explorer.exe.
- Warning: Registry changes are risky. Back up the registry before changing anything.
